System and method for completing private calls made to private numbers

摘要

An advanced intelligent network system for managing and routing telephone calls from a calling party to a subscriber to a privacy screening service. The system routes the calls according to whether the calling party number is known and public, in which case the call is terminated in a routine manner; unknown, in which case the system plays an announcement asking the calling party to record his or her name; or known and private, in which case the system asks the caller for permission to override his or her privacy before routing the call to the subscriber. The advanced intelligent network system stores the subscriber's number in a display text field, thus enabling termination of the call to the subscriber irrespective of whether the subscriber number is private or public.
